A narrow range of Nd:Eu:Gd chemical ratio around (Nd_0.33Eu_0.33Gd_0.28)Ba₂Cu₃O_y composition supports formationa special correlated pinning disorder (laminar structure) active especially at high fields. The irreversibilty field increased by means of this pinning agent about twice, to 14-15 T at 77 K.
